Being covered in soap bubbles wasn't his definition of a nice evening but he couldn't force himself to complain.
Merlin'a face was scrunched up in such a grimace that you could say just by looking that he must have tasted something especially foul. Frustrated golden eyes pinned Pendragon in his place but Merlin was quiet. Now, that'd be strange if Arthur didn't know the reason behind tightly closed mouth.
He wasn't jealous one bit, content with being only participant and not the main reason why his chamber was invaded by bubbles.
This was an excellent blackmail resource.
'Come oooooooon Merlin. Say something.'
His Court Sorcerrer shook his head but after a while a mischievous spark lit in his still golden eyes.
Arthur ducked but years of peace and good hunts really didn't make him as fast and agile as he would prefer. He turned left runnig from his best friend's hands and with undignified squeak slipped on one of many puddles on the floor of his chamber.
A moment and another squeak (not his) later Merlin landed right beside him, head first into a pile of bubbles. The king of Albion was sure that he heard some very clourfull words muttered by his unofficial brother. A moment after that the man moved and Arthur didn't get time to react. Face to face with each other the smaller of the two got good look at his Court Sorcerer. Still gold eyed and grimacing slightly with a pile of soap bubbles covering his hairs and part of his mustache Merlin looked comical. Arthur satreted to laught.
The last dragon lord smirked, leaned down until he was nose to nose with his King and opened his mouth...
... drowing Arthur with a magical stream of soap bubbles.
A little something because I've just remembered when I did a mix of soap and water in a tea cup and left it on a table. And our cups are made of dark glass. And my sister was sooo thirsty. Good I wasn't home at the time because she is scary as hell when angry.
